BOILER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 550,521, dated November26, 1895.

Application filed July 13, 1896.

To aZZ whom it may concern:

Be it known that I, DAVID MYERS, a citizen of the United States,residing at the city of Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements inBoiler-Cleaners, of which the following is a specification.

This invention relates to certain new and useful improvements inboiler-cleaners, and refers more particularly to that class of boilercleaners in which the refuse is collected by a skimmer and expelled fromthe boiler, being carried outwardly through a tube into a settling drumor chamber; and the invention consists in a skimmer supported upon asleeve, which sleeve is in turn supported by floats in position toreceive the refuse from the boiling water, the sleeve being retained inposition by means of the pipe which conveys the refuse out of theboiler.

The invention also consists in the use of an auxiliary separator locatedin the settling drum or chamber, whereby the refuse which is carriedinto the settling-chamber may be separated from the water which isreturned to the boiler, the device being so constructed that the refuseand the water carried from the boiler are deposited in a settling drumor chamber and the refuse is left in the settling drum or chamber whilethe water is returned to the boiler; and the objects of my inventionare, first, to thoroughly and efficiently separate the refuse from thewater in the steamboiler; second, to provide a skimmer which willautomatically adjust itself to the proper position within the boiler toreceive the refuse and to remove the same therefrom; third, to combinewith the settling-drum an auxiliary cleaner or separator constructedsubstantially as described. These objects I accomplish by means of themechanism illustrated in the accompanying drawings, in which- Figure 1is a sectional View of a steamboiler, showing my improved skimmer andalso showinga settling tank or chamber with my improved separatorarranged therein.

Fig. 2 showsa plan View of a skimmer constructed in accordance with myinvention de- Serial No- 555,889. (No model.)

tached from the tube which conveys the refuse from the boiler. Fig. 3shows a sectional View on line Y Y of Fig. 2, showing the position ofthe skimmer and floats with reference to the exit-tube which conveys theWater andthe arrows showing the direction taken by the water and refusein their passage from the boiler.

E represents the settling-drum, which receives the refuse from theboiler, and F represents the return-pipe, which conveys the water fromthe settling-drum back to the boiler.

B represents the skimmer, which is composed of a series of open passagesleading from the periphery of the skimmer to a central point-that is, tothe head or socket K.

B B represent the passages placed above the skimmer, which direct thewater and refuse to the openings 1) b, which openings allow the refuseto pass into the socket K. I prefer to construct my skimmer with siX ofthese passages B B but the number maybe varied. The socket K fitsloosely upon the lower end of the conduit-pipe O, and the skimmer, to-

gether with the socket K, is held at the proper position in the boilerby means of the floats H H. In the drawings 1 have shown four of thesefloats; but the number may be varied, and the operation of this part ofmy invention is such that as the water is raised or lowered in theboiler the skimmer is raised and lowered and always retained in theproper position to receive the refuse, which rises and is carried by thecurrents of water in the boiler. I also provide at the lower end of thepipe G small holes which will receive the water and refuse into the pipe0, from whence they are carried outwardly, as above described.

The bottom of the socket K is closed while the bottom of the pipe 0 ispreferably left open. By this construction I provide a skimmer which isautomatically adjustable to the required position at all times anddispense with everything in the shape of a joint or hinge, theskimmer-floats moving freely up and down, being retained in thatposition merely by the lower end of the pipe G.

I prefer to construct the conduits B B with their upper surfaces on acurve, as shown, while the skimmer proper forms the bottom of theseopenings.

D represents a cone-shaped enlargement at the lower end of the pipe 0,and the same receives the refuse and water which are carried through thepipe 0. I prefer to make the cone-shaped part D integral with therefuseseparator and not integral with the dischargepipe. This, however,is merely a question of convenience in construction.

N N N are a series of funnel-shaped receptacles placed around thecone-shaped opening 1), and the water and refuse which are conveyed tothe settlin g-drum through the pipe 0 pass down between the funnelshaped receptacles N N N,and the water in returning passes around theouter rim of the series of funnels N N N, as shown in Fig. 1 by thearrows, and any refuse which remains in the water passes into thesereceptacles N N N, from which it drops down by gravity through thedischargepipes P P, &c., and settles to the bottom of thesettling-chamber. In the example of my i11- vention shown in thedrawings I have shown six of these receptacles N N N; but the number maybe varied.

The settling-chamber E may also be provided with suitable means fordrawing off the refuse at the bottom; but inasmuch as such devices areold I have not deemed it necessary to illustrate them in the drawings.

In order to retain the separator in proper position in thesettling-drum, projections Q Q may be used of suflicient length to meetthe walls of the settling-chamber E. This will allow the water to risefreely around the outer rim of the separator to pass over and becomedeposited in the funnel-shaped receptacles N N N.

Having thus described my invention, what I claim to have invented, anddesire to secure by Letters Patent, is-

1. In a steam boiler cleaner, the combination with a settling chamber,of a pipe leadin g from within the boiler to the settling chamber, and askimmer adj ustably supported upon the end of said pipe within theboiler, and consisting of a receptacle having a fiat bottom and dividedinto a plurality of coneshaped vessels having their small ends sewhichare arranged around and connected to said sleeve and forming a passagefrom the boiler to the latter, and a float or floats connected to saidcone-shaped Vessels, substantially as described.

3. In combination with a boiler, a settling drum, a plurality offunnel-shaped receptacles within the settling drum, a suitable openingreceiving the water and refuse from the boiler and conveying the same toa point below the said funnel-shaped openings, a casting supporting thesaid funnel-shaped receptacles of form to correspond substantially tothe inner shape of the settling drum, openings at the bottom of each ofsaid funnelshaped receptacles for the discharge of the refuse gatheredtherein, and a return pipe adapted to convey the water freed from therefuse from the settling drum back to the boiler, substantially asdescribed.

i. In combination with a settling drum, an inlet pipe, an invertedfunnel placed within the said drum in which the said pipe opens, aseries of funnelshaped receptacles supported within the said drum andhaving open ings for the discharge of the refuse toward the bottom ofthe said drum, a broad opening at the top for the reception of therefuse received from the water arising from the drum to the pipe whichconveys the water back to the boiler, substantially as described.

5. In combination with a drum, an inlet pipe, an inverted funnel intowhich the said inlet pipe opens, an opening at the bottom of the saidfunnel, a series of funnel-shaped receptacles surrounding the saidopening, a space between the said funnels and the inner periphery of thesettling drum allowing the water to pass upward and over the saidfunnel-shaped receptacles, and a return pipe adapted to convey the waterfrom the said settling drum to the boiler, substantially as described.

6. In a steam boiler cleaner, the combination with a settling tank orchamber, of a pipe leading from within the boiler to within the settlingtank, a floating scum-remover freely surrounding the end of the pipewithin the boiler, and consisting of a plurality of radially arrangedcone-shaped vessels connected to a sleeve which surrounds the end of theoutflow pipe and forming passages from within the boiler to said pipe,an auxil- IIO iaryseparating device arranged upon the pipe hand and sealin the presence of two Wit- Within the settling tank and consisting of anesses.
